Patent CA-2077652-A1 (CA)
Title: Turbidity measurement
Inventor: JOYCE JOHN G
IPC: G01N21/15
Filed: 1991-03-06
Abstract: In measuring the turbidity of a liquid, especially for determin-ing water clarity in a water purification process in which after the ad-dition of flocculant the water is centrifuged, light is emitted as a dif-fuse beam from a light source (11) and the intensity of light reflected from gas bubbles in the liquid is detected by a photosensor (12). The light source and photosensor are incorporated in a probe (6) having transparent cylindrical wall (7) and sealed within a housing (1) con-fining a liquid receiving chamber (2) by a pair of seals (9) between which is formed a space (10) containing cleaning solution. An actua-for (18) is coupled to the probe (6) for reciprocating he probe relative to the housing and seals (9) for cleaning, deposits from the, wall (7).

Abstract: Mélange de matériau composite (141) renfermant des particules fluides de renfort dans un métal liquide solidifié à une vitesse de refroidissement supérieure à 15 degrés Celsius par seconde entre les températures dites << Liquidus >> et << Solidus >> de l'alliage de la matrice. La vitesse de refroidissement élevée confère une structure homogène au matériau composite solide. On veille à ne pas introduire de bulles de gaz (146) dans le matériau composite liquide pendant que le mélange est agité afin d'empêcher la ségrégation des particules. Pour les matériaux fondus visqueux, une couche de surface artificielle comme une toile de fibre de verre peut être utilisée afin d'éviter que des bulles soient emprisonnées pendant l'agitation précédant la coulée. De plus, les bulles de gaz sont éliminées du mélange liquide par filtration (151) et par écumage.

Title: Radiotelephone system controller
Inventor: TELL DANIEL F
IPC: H04Q7/24
Filed: 1992-10-13
Abstract: A controller (118) controls functions related specifically to radiotelephone signalling in a communication system. The controller (118) is physically dislocated from a switch (112) which performs all necessary routing of voice information from radiotelephone system-to-radiotelephone system and radiotelephone system-to-public switched telephone system (PSTN, 100). The controller (118) interfaces the switch (112) via an ISDN-type connection, essentially accessing the switch (112) transparently. This transparent access allows for common, generic switches (Class 5 switches for example) having predetermined user features such as Call Waiting, 3-Way Calling, etc. to be employed. Users of the radiotelephone system (125), via radiotelephone signalling processing by the controller (118), can access and utilize the predetermined features of the switch (112) as required.

Title: Surface Modified Porous Expanded Polytetrafluoroethylene and Process for Making
Inventor: ZUKOWSKI STANISLAW L
IPC: C08J7/00
Filed: 1992-06-08
Abstract: Porous expanded polytetrafluoroethylene material having a microstructure of nodes interconnected by fibrils wherein a surface of the material has been modified to have increased hydrophobicity as indicated by having a water droplet roll-off angle of less than about 10 degrees in comparison to a typical roll-off angle of greater than about 12 degrees for the unmodified material. Under magnification, the surface morphology may be indistinguishable from that of the unmodified precursor material. The modification is preferably done by exposing the surface to radio frequency gas plasma discharge with a reactive etching gas for a lengthy amount of time such as about ten minutes. If surface etching is continued beyond a time adequate to produce the highly hydrophobic behavior, then the surface morphology includes the appearance of broken fibrils. Still further treatment results in complete removal of fibrils from the surface so that under magnification the surface has the appearance of freestanding node portions not interconnected by fibrils but rather having open valleys disposed between the freestanding node portions.

Title: Low profile radiant heating element
Inventor: MARKUM RANDALL
IPC: H05B3/06
Filed: 1994-06-02
Abstract: Abstract of the Disclosure Electrical heating apparatus for use in an electric range having a glass/ceramic type cooking top.  A pan is mounted beneath the cooking top, and an electrical heating element is installed in the pan.  When electrical current is supplied to the element, the heat produced is directed at an underside of the cooking top to uniformly heat a defined area of the top.  The heating element is installed on, and attached to, a contoured upper surface of the support.  The support is made of a heat reflective material which directs heat radiated by the heating element toward the underside of the top.  Spacers space the heating element from the underside of the cooking top.  Because the heating element is of a positive temperature coefficient material, minimum separation is required between the heating element and the cooking top.
